Observe means notice carefully, while overlook can mean fail to notice.
Correct: I observed the mistake, not overlooked it. - Using formal O verbs in casual speech
Some verbs like obtain or originate sound formal in daily conversation.
Better choice: Use get instead of obtain in casual settings. - Forgetting prepositions in phrasal verbs
